I had my engine mount and retractable gear legs on my 47 Bellanca Cruiseair powder coated when I restored the plane in 2000. I was told that cracks would not show by some but the APIA I used said it was alright. A year ago I had oil on the floor below my gear. I pulled the gear and with no trouble found the gear cracked at the top. Cleaned it off welded it and had the gear powder coated again.

Most powder coating materials that I have used are thin enough and brittle enough that you will have cosmetic issues with the powder coating if you have stress cracks or excessive deflection. Motorcycle frames, drag car (funny and top fuel) frames are frequently powder coated because it takes a lot of chemical abuse, looks good, and doesn't have the inherent process induced stresses caused by electroplating (think chrome). Another el-cheapo powder coating system is to find a used commercial gas oven and vent it properly; better and more uniform temperature control as well. With the right oven, you could even powder coat an engine mount. Mark W.

Can anyone shed some light on this? Tony King Queensland Australia On 19 January 2011 08:55, Craig Williams <kr2seaf...@yahoo.com> wrote: > Anyone else built an el-cheapo powdercoat system.
